Methods: One hundred and eighty male rats were divided into three groups, which were submitted to the following systemic treatments: physiological saline solution (PSS); CIS and 5FU. Each group was subdivided into two subgroups: without (NEP) and with (EP) induction of EP. Animals were euthanized at 3, 5 and 7 days post-treatment. Histological, histometric (percentage of bone in the furcation [PBF]) and immunohistochemical (for tumour necrosis factor-α, interleukin-1β and receptor activator of nuclear factor-κB ligand) analyses were performed. Data were statistically analysed. Results: CIS-NEP and 5FU-NEP showed more inflammation than PSS-NEP at 3, 5 and 7 days. CIS-EP and 5FU-EP showed more inflammation and lower PBF than PSS-EP at all periods of evaluation. 5FU-EP showed lower PBF than CIS-EP at 5 and 7 days. Conclusion: 5-FU and CIS exacerbated periodontal inflammation and aggravated the progression of EP in its early stages.457-469engalveolar bone lossantineoplastic agentscisplatinfluorouracilperiodontal diseaseperiodontiumArtigo10.1111/jcpe.13101Acesso restrito2-s2.0-850649318924408095517346846477444711812734683998700975720730000-0003-4859-0583
